SAN DIEGO -- On Sunday, the Dodgers optioned shortstop Miguel Rojas and pitcher Carlos Frias to the minors to free roster spots for Hyun-Jin Ryu and Juan Uribe to come off the 15-day disabled list and start the game in San Diego. But those two young players won’t be absent for long.

On Tuesday, after the Triple-A season ends, both Rojas and Frias will return to join the Dodgers before their game against the Washington Nationals. Before that happens, though, on Monday, the Dodgers will get five or six extra players arriving from the Albuquerque club. Some of those players likely to be called up: catcher Tim Federowicz, outfielder Joc Pederson, pitcher Yimi Garcia and infielders Alex Guerrero and Erisbel Arruebarrena.

The Dodgers also have the possibility of making a trade between now and 9 p.m. PT to acquire a player from another organization who would be eligible for postseason play. They attempted to trade for slugger Adam Dunn, but the Chicago White Sox instead traded Dunn to the Oakland Athletics. Dodgers general manager Ned Colletti has also had discussions about relievers.

“I’ve heard some names floating around and there’s still a possibility of something getting done,” Dodgers manager Don Mattingly said. “I’m not sure if that’s going to happen.”
